I VEHICLE-WHEEL TIRE.

Specification of Letters Patent.

' To all whom it may concern:

Be it known that I, FRIEDRICH WIECHARD, a subjectof the German Emperor, and resident of Hanover, Germany, have invented certain new and useful Vehicle- Wheel Tires, of which the following is a specification.

-This invention relates to the fixation of solid rubber tires on the rims of motor car or other wheels.

It consists in inserting between the tire and the rim flange rings, rubber pads the object of which is .to hold the tire securely but elastically on the rim and between the flanges of the latter.

T e accompanying drawin given by way of exam 1e, shows the pre erred embodime'nt oft e invention and in this drawing :-v I Figure 1 shows a cross section of the tire and of its mode of fixation; Fig 2 is a perspective view of a section of the tire and Fig. 3 a similar view of a section of a flange ring of the rim. v,

The tire A is held upon the rim E or 7 rather on the rim hoop C by the flange rin TE:

D D and bly the connecting bolts tire preferab y rests upon the rim hoo not with its entire base but only with a rib F.

This arrangement contributes to increase the elasticity. -N ow, according to the principles of the present invention rubber rings or pads B B are interposed between the tire A and the flange rings D D the tire ,as well as the inner surface of the flanges being serrated with a view of ascertaining a better engagement and astronger hold and to prevent the tire creeping. The pads B B hold, it is true, the rubber tire in .an absolutely sure and strong manner. However the connection is not absolutely rigid, and affords the tire a certain elastic movability inside the rim. This elasticity is still increased by the bearing rib F in the form of a ring which favors the movability of the tire especially in the radial direction. If, after a long use, the connection would get loose, the rubber pads may easily be replaced by new ones. is not attacked nor injured by the tightening rings.

Having now fully described my said invention, what I claim and desire to secure by Letters Patent is In a vehicle wheel, the combination with the fell annular flanges secured thereto and pro ectin radially therefrom, the inner faces of said anges bein serrated at points beyond the eriphery o the felly, a solid tire, rovided on its inner surfacewith an annular rib reduced in width with respect to the width of the base or inner surface of said tire and normally holdin the base thereof out of contact w1th the fe ly, the side faces of said tire being serrated, and annular rings of yielding material having their opposite faces serrated and inter ose'd between the serrated faces of said tire, said rings having an internal diameter greatenthan the diameter of said felly, and normally out of contact therewith."

In testimony whereof I- have hereunto set my hand in presence of two witnesses.
